News Detail
  • SF6 gas in medium-voltage switchgear | TD - Siemens USA

    SF6 has been used extensively in non-electrical applications. Since SF6 is inert, it is very attractive to the magnesium industry. Magnesium reacts spontaneously in the presence of oxygen, so a heavier-than-air cover gas is used to isolate the molten magnesium from oxygen as the magnesium cools.
